[0002] A flow regulating valve is a control component in a pipeline fluid transportation system, which mainly controls the flow rate, pressure, etc. effectively by changing the opening degree of the valve. At present, the flow regulating valves on the market are mainly piston type flow regulating valves, which control the opening degree of the valve by the forward and backward movement of the piston inside the valve body. The flow regulating valve has a large volume and occupies a large space, and some pipelines cannot be installed normally due to space limitations, which has certain limitations. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an electric flow regulating valve device with a simple and compact structure, small occupied space, wide application range, and good usability.

[0004] To solve the above technical problem, the utility model adopts the following technical solutions:

[0005] An electric flow regulating valve device includes a valve seat, a valve core, a valve cover, and a driving motor. The valve core is arranged inside the valve seat, the valve cover and the driving motor are arranged on the valve seat. The valve seat has a first end and a second end. The valve core is provided with a communication port. The valve core is circumferentially and fixedly connected to the output end of the driving motor. The driving motor drives the valve core to rotate, so as to open or close the water path between the valve seat and the valve core.

[0006] A magnet induction sheet is circumferentially and fixedly connected to the output end of the driving motor. A reed switch sensor is arranged on the valve seat. The driving motor drives the magnet induction sheet to rotate. When the magnet induction sheet faces the reed switch sensor, the valve core is in a fully open state.

[0007] As a further improvement of the above technical solution:

[0008] A temperature sensor for detecting the water temperature is arranged inside the second end.

[0009] A hexagonal joint and a thread are sequentially arranged on the outer wall of the second end along the water flow direction.

[0010] The valve core includes a valve inner communication part and an extension connection part. The communication port is located on the valve inner communication part. The extension connection part passes through the valve cover and is connected to the output end of the driving motor.

[0011] A valve cover sealing ring is arranged between the valve cover and the valve seat. A valve core sealing ring is arranged between the extension connection part and the valve cover.

[0012] The valve seat is provided with a valve cover mounting portion and a drive motor mounting portion. A fastener passes through the valve cover and is inserted into the valve cover mounting portion to fixedly connect the valve cover to the valve seat. The fastener passes through the drive motor and is inserted into the drive motor mounting portion to fixedly connect the drive motor to the valve seat.

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] The electric flow regulating valve device of the present utility model includes a valve seat, a valve core, and a drive motor. The valve core is rotatably arranged in the valve seat, and the drive motor drives the valve core to rotate, thereby adjusting the opening degree of the valve by the rotation angle of the valve core, and then effectively controlling the flow rate. It replaces the technical solution of controlling the opening degree of the valve by the forward and backward movement of the piston in the prior art. At the same time, a magnet induction sheet is fixedly connected circumferentially to the output end of the drive motor, and a reed switch sensor is arranged on the valve seat. The magnet induction sheet rotates synchronously with the valve core. When the magnet induction sheet faces the reed switch sensor, the drive motor stops rotating. At this time, it is the zero point of the drive motor, which is convenient for positioning the initial angle of the drive motor. At this time, the valve core is in the fully open state. When the direction of the magnet induction sheet is parallel to the water flow direction, the valve core is in the fully closed state. Users can directly understand the opening degree of the valve by observing the position of the magnet induction sheet. It has the advantages of simple and compact structure, small occupied space, wide application range, and good use convenience. Description of the Drawings

Specific implementation mode

[0027] The following further elaborates on the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0028] As Figures 1 to 7As shown, the electric flow regulating valve device of this embodiment includes a valve seat 1, a valve core 2, a valve cover 3 and a driving motor 4. The valve core 2 is arranged in the valve seat 1, and the valve cover 3 and the driving motor 4 are arranged on the valve seat 1. The valve seat 1 is provided with a first end 101 and a second end 102, and the valve core 2 is provided with a connecting port 201. The valve core 2 is circumferentially fixedly connected with the output end of the driving motor 4, and the valve core 2 is driven to rotate by the driving motor 4 to open or close the water path between the valve seat 1 and the valve core 2; the output end of the driving motor 4 is circumferentially fixedly connected with a magnet sensing sheet 5, and a reed switch sensor 6 is arranged on the valve seat 1. The magnet sensing sheet 5 is driven to rotate by the driving motor 4. When the magnet sensing sheet 5 is opposite to the reed switch sensor 6, the valve core 2 is in a fully open state. The electric flow regulating valve device comprises a valve seat 1, a valve core 2 and a driving motor 4. The valve core 2 is rotatably arranged in the valve seat 1. The driving motor 4 drives the valve core 2 to rotate, so as to adjust the valve opening by the rotation angle of the valve core 2, thereby effectively controlling the flow rate, replacing the technical solution of controlling the valve opening by moving the piston back and forth in the prior art. At the same time, the output end of the driving motor 4 is circumferentially fixedly connected with a magnet sensing piece 5, and a reed switch sensor 6 is arranged on the valve seat 1. The magnet sensing piece 5 rotates synchronously with the valve core 2. When the magnet sensing piece 5 is opposite to the reed switch sensor 6, the driving motor 4 stops rotating. It is the zero point of the driving motor 4, which is convenient for locating the initial angle of the driving motor 4. At this time (when the direction of the magnet sensing piece 5 is perpendicular to the direction of the water flow), the valve core 2 is in a fully open state, and the water flow value is maximum. When the driving motor 4 drives the magnet sensing piece 5 to rotate clockwise, the water flow area of the valve core 2 becomes smaller and smaller, and the water flow value becomes smaller and smaller, until the direction of the magnet sensing piece 5 is parallel to the direction of the water flow, the valve core 2 is in a fully closed state. The user can intuitively understand the opening of the valve by observing the position of the magnet sensing piece 5. It has the advantages of simple and compact structure, small space occupation, wide application range and good convenience.

[0029] Preferably, a temperature sensor 7 is provided in the second end 102, which can detect the temperature of water when it flows through and output a feedback signal. When it is detected that the water temperature is lower than the target temperature, a signal is sent to the control module to reduce the water flow area of the valve core 2, reduce the water flow value, and ensure that the temperature is raised to the target temperature.

[0030] Preferably, the outer wall of the second end 102 is provided with a hexagonal joint 8 and a thread 9 in sequence along the water flow direction. In this embodiment, the first end 101 is connected to the instant water heater, and the second end 102 is connected to the external device through the hexagonal joint 8 and the thread 9, so that the electric flow regulating valve device can be used as a water nozzle of the instant water heater, which can improve production convenience and reduce costs.

[0031] Preferably, the valve core 2 includes an internal communication portion 202 and an extended connection portion 203. The communication port 201 is located on the internal communication portion 202. The extended connection portion 203 passes through the valve cover 3 and is connected to the output end of the drive motor 4, facilitating quick and easy disassembly and assembly.

[0032] Preferably, a valve cover sealing ring 10 is provided between the valve cover 3 and the valve seat 1, and a valve core sealing ring 11 is provided between the extended connection portion 203 and the valve cover 3, which can effectively improve the sealing performance between the valve seat 1, the valve core 2 and the valve cover 3, prevent leakage of the electric flow control valve device, and has high reliability.

[0033] Preferably, the valve seat 1 is provided with a valve cover mounting portion 103 and a drive motor mounting portion 104. The fastener passes through the valve cover 3 and is inserted into the valve cover mounting portion 103 to fixedly connect the valve cover 3 to the valve seat 1. The fastener passes through the drive motor 4 and is inserted into the drive motor mounting portion 104 to fixedly connect the drive motor 4 to the valve seat 1. The valve seat 1 is also provided with a reed switch sensor mounting portion 105 and a temperature sensor mounting portion 106. The reed switch sensor 6 is inserted into the reed switch sensor mounting portion 105, and the temperature sensor 7 is inserted into the temperature sensor mounting portion 106, which can effectively improve the connection stability of each component on the valve seat 1, and is quick and easy to disassemble and assemble, with high maintenance efficiency.

[0034] Preferably, a snap ring 12 is provided on the outer wall of the first end 101. In this embodiment, the snap ring 12 is provided on the outer wall of the first end 101 as a quick-release structure, which can effectively fix the object, prevent axial movement, reduce wear and movement resistance at the same time, and has the advantages of small size, light weight, convenient installation and maintenance.
